IMPROVEMENT IN BUNGS.

Specification forming part of Letters Patent No. 217,287, dated July 8, 1879; application filed May 29, 1879.

To all whom it may concern:

Be it known that I, HENRY HOLDER, of the city of Baltimore and State of Maryland, have invented a new and Improved Bung for Barrels; and I hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a perspective view of the bung and bushing. Fig. 2 is a sectional view of the bung separated from the bushing and the holding devices withdrawn. Fig. 3 is a vertical section through the device on line a: a; of Fig. 1. Fig. 4 is a side view of the fastening device as seen through the bung.

The object of my invention is to provide a cheap and readily-applied bung for beer and other barrels; and it consists in a bushing having a recessaround its interior edge, combined with a hung provided with bell-cranklever catches projecting from its periphery, and operated by a thrustpin operating in the center of the bung, to throw the levercatches beyond the dead-point, and thereby fasten the bung.

In order that those skilled in the art may make and use my invention, I will proceed to describe the exact manner in which I have carried it out.

In the said drawings, A is a bushing set into the barrel, and provided on its interior circumference, near its outer end, with a recess, a. The bung B is made to fit into this bushing. This bung is cast hollow, and has a slot,

0, on each side, in which to provide a space for two lever catches for securing the bung to the bushing. The bung B is cast hollow and provided at its lower end with a proper packing, h, and the center of its upper surface is centrally perforated to secure a plunger-rod, D, provided with a head, d, which fits flush in the opening. Pivoted to the plunger-rod are two lever-links, e e, which engage with bell-crank levers ff at i t. These levers are cast with a rib, f, which passes between two lugs, g g, cast on the sides of two opposite openings, 0 o, in the bong, and at the angle of the levers they are rounded, as shown, and bear on top of the lugs g g as a fulcrum. When the plungerrod is drawn out of the hung, the links 0 e draw the cam-levers so their ends a a lie flush with the side of the bung, as seen in Fig. 2. The bung then being pressed into the bushing until well home, the thrustrod is forced down until the ends a a catch under the rib forming the recess a, and passing the levers beyond the dead-point of the cam, the bung is secured.

The head at is provided with openings (1 d, into which to insert a sharp instrument to withdraw the plunger-rod.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The hollow bung B, provided with slots 0 0, thrust-rod D, links 0 e, and bell-crank levers ff, in combination with a bushing, A, provided with an offset, a, substantially as de scribed.
